Definitions

  • the solution relates to the field of mechanical engineering, namely, engine-building, and can be used in the cylinder-piston group of internal combustion engines.
  • the closest technical solution selected as a prototype, is a compression ring for the RF patent for useful model JSfe 151610 F02F 5/00 publ. 04/10/15. in BI LE, containing two steps of different heights. This design takes into account the wear ring in height, which is the reverse of the newly manufactured ring.
  • the specified ring design does not take into account the fit of the ring to the cylinder, which is dependent on the shape of the rubbing surface of the cylinder, which varies with skews and wear of the piston-ring-cylinder mates.
  • the task of the proposed solution is to improve the design of the ring.
  • the technical result of using the solution is to improve the tightness of the cylinder-piston group of parts.
  • This solution compared with the prototype, takes into account the fit of the outer surface of the ring to the cylinder mirror.
  • FIG. 1 depicts a pair of ring-cylinder.
  • FIG. 2 shows the position of the lock and the ring hub relative to the piston pin.
  • the ring (Fig. 1) contains the inner surface 1 and the outer surface 2 in contact with the mirror of the cylinder 3.
  • Pairing works as follows.
  • the elasticity of the ring and the pressure of gases 4 press the outer surface of the ring to the cylinder mirror.
  • the fit density depends on the contact form of the rubbing surfaces. Taking into account manufacturing errors, wear and misalignment, the contact of the ring and cylinder is, in general, a non-circular and non-cylindrical surface.
  • the stress concentrators on the inner surface 5 directionally reduce the ring stiffness in order to copy the outer surface of the cylinder mirror ring and increase the tightness of the cylinder-piston group.
  • the most common form of contact between the ring and the cylinder is an oval with a larger axis perpendicular to the piston pin 6 (Fig. 2).
  • the fit of the ring and the cylinder along the oval line depends on the positions of the lock 7 and the stress concentrator 8.
  • the minimum radius of the outer surface of the ring ⁇ t1p perpendicular to the axis of the piston pin is provided by the lock, on the other hand the stress concentrator 8 with the minimum thickness of the ring * ⁇ min ⁇ Maximum contact radius
  • the oriented position of the lock and the stress concentrator relative to the piston pin minimizes the rotation of the ring, improves the running-in and tightness of the cylinder-piston group of parts.

Abstract

La solution technique concerne le domaine des constructions mécaniques et notamment la construction de moteurs et peut s'utiliser dans un groupe de pièces groupe cylindres-pistons d'un moteur à combustion interne. L'anneau, qui comprend des surfaces externe et interne, comporte à la surface interne de l'anneau des concentrateurs de tensions pour copier par la surface externe de l'anneau le miroir de cylindre. Le résultat technique consiste en un plus grande étanchéité du groupe cylindres-pistons des pièces.
